The disclosure relates generally to a multiple use mask for covid-19 protections and in particular to a complete face seal multiple use mask.
Facial masks are common in various medical settings to reduce the spread of disease, in the building construction trades to reduce breathing intake of dust or fumes, and in travel and other scenarios to reduce contagious disease spread. Currently, due to the covid-19 pandemic, people are wearing various types of masks designed to prevent droplets containing the virus from gaining access to the nasal passages or mouth of a user. Many people are wearing or required to wear facial masks while at work, shopping, and walking outside and many other non-medical situations. Some people were required or voluntarily wore facial masks for extended times—sometimes for multiple hours and sometimes for 8+ hours per day.
Facial masks have typically been constructed using elastic straps which loop around the ears or the back of the head to hold the mask itself against the face. This design can result in wearers suffering back-of-the-ear irritations, where the elastic straps irritate the skin behind the ears. The straps often can become uncomfortable, especially for extended-time wearers or every-day wearers. Facial masks which are held against the face by ear straps often have “air gaps” around the edge of the mask, allowing unfiltered air to enter in or out of the wearer. One solution has been to pull the mask tighter against the face, which does create a better seal/smaller gaps, however wearing a tight face masks typically makes the face mask less comfortable to wear and can leave impression marks in the skin.
Thus, the problem with most of these masks is that they do not create a complete facial seal meaning that the virus can still exit or enter the mask because there is not a complete facial seal. Furthermore, most of these masks use straps that go around the ears of the user or the back of the head of the user which is uncomfortable and results in people removing the mask at the wrong times (such as when still inside in an enclosed area with a large number of other people) or not wearing the mask at all. Thus, it is desirable to provide a mask that do not require straps and seals the face.
There have been other uses for an adhesive to adhere an item to the skin of the user. For example, nasal strips meant to open the nasal passages or strapless brassieres use some form of adhesive to adhere to the skin pull the skin up on the nose and thus open the nasal passages. The adhesive on a strapless brassiere adheres to the skin and keeps the brassiere up and covering the breasts of the wearer. None of the uses however, have contemplated using an adhesive for other purposes.
In other fields, such as notes that may be stuck to a surface, a “weak” adhesive may be used that can be used to stick the note multiple times to a surface since the adhesive can be reused multiple times. Thus, it is desirable to provide a facial mask that uses a weak adhesive to completely seal the face and it is to this end that the disclosure is directed.
The disclosure is particularly applicable to a face mask that can be used multiple times for protection against Covid 19 and it is in this context that the disclosure will be described. It will be appreciated, however, that the mask may be manufactured of different materials, have different sizes or shapes and have other features that are all within the scope of the disclosure.
The disclosure is directed to a facial mask that completely seals the areas of the face that improves wearing comfort, avoids ear irritations, and creates a complete seal of the mask against the face. The facial mask may be implemented for both non-medical grade (cloth) masks and/or medical-grade (N95 or similar) masks. Furthermore, different materials can also be utilized with this invention to achieve disease-spread-reducing, particulate filtering, fume-reducing, or other goals/criteria. Now, several examples of embodiments of the facial mask will be described.
The adhesive may be a weak adhesive and may be in the form of a strip of adhesive that is affixed to the covering portion 202. For example, the adhesive may be double sided and one side is stuck to the covering portion 202, the adhesive may be sewed to the covering portion or attached to a hook and loop structure, such as Velcro or similar material with the purpose of the hook and loop or similar fastener allows the facial mask material/covering to be temporarily remove/replaced by the wearer, with the tape/adhesive continuing to be attached to the face (for example to eat a meal or take a drink). The first side of the adhesive does not release from the covering portion 202 while the other side adhesive is pressed onto the face to secure the mask to the face. When the mask 200 is placed over the mouth and nose of the user, the adhesive 204 sticks to the skin of the user to completely seal the mouth and nose of the user. The adhesive may be manufactured such that it can be easily removed from the face of the user and then replaced onto the face of the user without significantly degrading the stickiness as above.
The adhesive may be a weak adhesive and may be in the form of a strip of adhesive that is affixed to the covering portion 302. For example, the adhesive may be double sided and one side is stuck to the covering portion 302, the adhesive may be sewed to the covering portion or attached to a hook and loop structure, such as Velcro or similar material with the purpose of the hook and loop or similar fastener allows the facial mask material/covering to be temporarily remove/replaced by the wearer, with the tape/adhesive continuing to be attached to the face (for example to eat a meal or take a drink). The first side of the adhesive does not release from the covering portion 302 while the other side adhesive is pressed onto the face to secure the mask to the face. In an alternate embodiment, the adhesive, such as a skin-friendly adhesive, may be sprayed or otherwise deposited onto the skin of the face of the user or directly onto the mask material so that the mask may be completed sealed onto the face of the user. In this alternative embodiment, no adhesive tape/strip is needed to achieve the complete face sealing.
This embodiment of the mask 300 also may have a wire mesh attached into the mask, such as sewn into around the edge of the mask, to provide shape-forming rigidity to the mask 300. The shape forming material may be other materials, such as silicone, plastic, etc. that can hold a shape and may also be used to keep the filter/cloth off of the lips (avoid touching lipstick, make it easier to speak, etc.). When the mask 300 is placed over the mouth and nose of the user, the adhesive 304 sticks to the skin of the user to completely seal the mouth and nose of the user. The adhesive may be manufactured such that it can be easily removed from the face of the user and then replaced onto the face of the user without significantly degrading the stickiness.
The adhesive may be a weak adhesive and may be in the form of a strip of adhesive that is affixed to the covering portion 402. For example, the adhesive may be double sided and one side is stuck to the covering portion 402, the adhesive may be sewed to the covering portion or attached to a hook and loop structure, such as Velcro or similar material with the purpose of the hook and loop or similar fastener allows the facial mask material/covering to be temporarily remove/replaced by the wearer, with the tape/adhesive continuing to be attached to the face (for example to eat a meal or take a drink). The first side of the adhesive does not release from the covering portion 402 while the other side adhesive is pressed onto the face to secure the mask to the face.
This embodiment of the mask 400 also may have a wire mesh attached into the mask, such as sewn into around the edge of the mask, to provide shape-forming rigidity to the mask 400 that can fit to the 3 dimensional shape of the face. When the mask 400 is placed over the mouth and nose of the user, the adhesive 404 and/or anchor points 406 sticks to the skin of the user to completely seal the mouth and nose of the user. The adhesive may be manufactured such that it can be easily removed from the face of the user and then replaced onto the face of the user without significantly degrading the stickiness.
Each of the embodiments shown in
Furthermore, each embodiment of the mask may have different sizes to accommodate different size and shape faces. For example, the facial mask may have an overall circular, elliptical, oval, square, and/or elliptical shape with both sides curving upwards (to approximate a smile shape), or in any other shape, for example to visually create a company logo (for example a circular body with two “ears” in the upper corners—for example to appear as mouse with two ears shape). As shown in the above figures, the mask may be a single piece or made from two pieces. Also, each embodiment may have advertising on an outside surface of the mask, an image and/or writing on the outside of the mask. Thus, in different embodiments, the mask may have a consistent color across the outside of the mask, different colors, designs, patterns, etc on the visible-to-the-world side of the mask. For example, the outer surface of the mask may have cosmetic patterns, colors, and shapes, such as a brand or company logo, patterns, or shapes.
Each of the above masks and the mask shown in
In some embodiments, the mask may have the adhesive or “tape” on the outside-side of the mask, positioned such that the single-sided tape approximately half covers the facial mask material, with some of the tape extending beyond the edge of the mask, allowing the tape material to then adhere to the skin outside of the area covered by the facial mask material.
Each of these masks 100-400 may be made of a typical mask material, such as a fine mesh of synthetic polymer fibers, such as a nonwoven polypropylene fabric. Each mask 100-400 may also be made of a cloth material and may have one or more folds in the mask that allows the mask to expand to accommodate a wider range of face sizes or to accommodate stretching/expansion of the mask. Alternatively, each mask 100-400 may be made of material that itself may contain one or more folds to accommodate stretching/expansion.
Each of the embodiments of the mask above or shown in
In one embodiment, any of the masks may be folded/sewn in areas so the facial mask may be shipped/stored flat or minimal height. Then, when the mask is applied to the face the folded areas unfold to better cover to the typical contours of the nose/mouth of the user. The masks may have a Caucasian skin color on an outside surface of the mask. In other embodiments, the mask may come in different colors to better blend with black, dark, or other colors and shades to match the wide-variety of human face color/tones.
In some embodiments, the filter element 604 may further comprise an anti-sticking cloth 604A, a first stage filter 604B, an activated carbon layer 604C, a second stage filter 604D and a second anti-sticking cloth 604E that are stacked together and are replaceable. The filter element 604 may typically be available commercially as a pre-manufactured “sandwich” of the multiple layers 604A-604E. Then, the “filter” pre-manufactured with the five layers is replaced. In other embodiments, the filter element 604 may have more or fewer layers, may have a different type or types of active layers (carbon or otherwise), and the filter element 604 and its constituent layers/parts may be adjusted depending on the target particles (virus, smoke, fumes, dust particles, etc.). being filtered. Furthermore, the filter layers may be made from electro-cloth filters, nano-filters, HEPA filters, silver-based filters, etc.
As an alternative embodiment to the embodiments shown above in which the adhesive bond/strip goes around the periphery of the mask, the mask may form a complete face seal with the combination of adhesives and other materials. For example, the mask may have a combination of adhesives in some portions of the face-to-mask seal and non-adhesive but air-blocking insulators (1-sided sticky foam for example) in other parts. For example, the mask forms the tight, complete seal in which adhesives are used for some portions of the seal as it goes around the face and then the insulators, such as piece of foam with one side having an adhesive to adhere to the covering, may be used to “fill in the gaps” between sections of adhesive as the seal goes around the face. As another alternative, the adhesives form an incomplete face seal to hold the mask on to the face, but not necessarily to form an air-tight seal. For example, there could be 4 or 5 adhesive points which hold the cloth covering on to the face and holds it in place over the nose/mouth, and forms a majority seal but not necessarily an “air tight” seal.
In some embodiments, the mask may include one or more valve or other air-flow limiting or switching device (to allow for greater unidirectional airflow rates). In some embodiments, the facial mask covering may extend over the skin slightly past the adhesive area/region to allow for a finger to easily grab this extra “tab” to allow easy mask removal from the face. For example, such a tab be placed along the bottom (chin-facing) side of the mask.
In some embodiment, the facial mask have “shape forming” material added to, in, formed on or attached to the face mask covering material, to aid in the covering conforming to either a pre-formed shape (i.e. the 3 dimensional shape around the nose), or user-conformed shape. Such “shape forming” forming materials may be continuous, semi-continuous, or limited (strips), in one multiple directions (for example in a mesh combined of multiple strips in parallel and/or different directions) to allow the user to conform (custom shape) the mask to a rigid, or semi-rigid, or shape to customize the mask to conform to that user's face shape. Such “shape additive” material could be composed of one or more metal areas, wire mesh (similar to a metal wire fence) metal, plastic, or other bendable materials, either pre-formed at the factory to a standard facial shape, or with user-formable materials to allow the user to custom-shape the semi-rigid material to the custom size/shape of his/her face. The facial mask may have any combination of one or more of the above shapes, colors, valves, and/or features, elements, adhesives or adhesive mechanisms.
In some embodiments, the facial mask may have one or more “hinge points” added to the filtering material, on, or attached to the face mask covering material, to aid in the temporary lift up/away from the mouth, for purposes of eating, drinking, talking on the phone, etc.
